Story
Note that this is the same storyline as from the original Omega and The Azure Witch event.

Wol returns again to the Tower of Trials, and is greeted by Vox who is thinly guised as the departed Voyd. Vox explains that a foul witch has extinguished Voyd and taken over his tower. The witch has already brough her own demons into the tower. Vox wants these demons removed and the order restored. Wol hates being used, but doesn't see much choice in the matter.

As Wol works his way up the tower, it's obvious that Vox is keen to see this woman destroyed. He's not coy about it, insisting that Wol kill her NOW. The witch, for her part, is much more circumspect. She says anyone out to kill her is her enemy, much like Voyd... but isn't prepared to declare Wol among those enemies just yet.

At the peak of the tower, the witch thanks our warrior for showing her that she needs to get stronger. In gratitude, she presents Wol with a small curse -- a kiss -- and tells him that her name is Meia. Wol will never forget her name. Echo splutters as Meia disappears, and Wol merely notes that he smells the fresh ocean tide.

Event Map
"The Tower of Trials looms in the space between dimensions. Only the strong may hope to reach its highest levels. Battle the Azure Witch and her army of fiends. Defeate the mechanized killer Omega!"

- World Map description

The ladder is composed of 25 steps up, with each step progressively harder than the last. There are two possible paths: The player cannot go downward in levels on their first trip, but may teleport to any of the central column (0, 10, 20, 30, 40) once the pinnacle has been reached.
 * The long path steps up 2 "floors" at a time, leading 25 total areas to the pinnacle.
 * The shortcut path steps up 10 "floors" at a time, leading 5 areas to the pinnacle.

Omega (Dark) is the last foe for every area.

After completing the ladder, the player enters the "Phantasmic Coil" areas. This is a set of 5 areas that repeat in an infinite loop, also with an increasing difficulty with each area finished. On these levels, a Prize of x3 is handed out for each loop of 5 completed.

There are 31 total areas and 6 treasure chests. Since the last treasure chest (in the Phantasmic Coil) automatically regenerates, the region can technically never be completed.
